UNITED STATES AUGUST KLONECK, OF NEW YORK, N. Y.

- EXPLOSION-MOTOR.

To all w ham it may concern: 7

Be it known that I, Aucus'r J. KLoNEox, a citizen of the United States, and a resident ofNew York, in the county and State of New York, have invented certain new and useful Improvements in Explosion-Motors, of which the following is a specification.

This invention relates to explosion motors and more particularly to that of a two cycle en ne.

ne object of the invention is to provide a novel arrangement of ports and channels to obtain a better discharge of'burned gases from an engine cylinder.

Another object of the invention is to interpose unmixed air between the exhausting gurned gases and a fresh charge of a cylin- A still further object of the invention is to heat the new charge and to cool with the same the piston and cylinder of the engine.

With the above and other objects in view, I have invented the improvements illustrated in the accompanying drawings in which Figure 1 is a sectional view of a motor cylinder, showing a piston at the extreme outstroke of the same. Fig. 2 shows the piston at the innermost positlon in the engine cylinder. Fig. 3 is a sectional view of a modified arrangement of ports and channels for a motor cylinder.

Like reference characters indicate like parts throughout the specification and in the drawings in which 1 indicates a cylinder, 2 a piston, 3 a connecting rod and 4 a crankshaft; the latter rotates within the crankcase 5. The cylinder 1 is provided with an exhaust port 6 for the explosion chamber 7, an inlet port 8 to the crank case 5 and an extra air port 9 into a chamber 10 of the crankcase 5; further a channel 11 with two ports 12 and 13, opening to the combustion chamber 7 of the cylinder and the crankcase 5, respectively. The piston 2.

chamber 7 is charged with an unexploded supply of gas mixture from the crank case 5 by means of the chamber and port 10, driv- Application filed December 29, 1915, Serial No. 69,226. Renewed December 13, 1920. Serial No. 430,552.

hot piston 2, further through port 18, the

channel 11 within the jacket of the cylinder I and the port 12 into the combustion chamfor the cylinders enters the same at the top of the cylinder while the exhaust port is at lowest position of the piston, it is obvious that the exploded gas will be completely driven from the combustion chamber of the cylinder. Further, as the extra air enters first the combustion chamber, it forms a noncombustible body between the exploded and unexploded gases, preventing a backfire of the engine and an escape of gas mixture through the exhaust.

In Figs. 1 and 2, the piston 2 is provided with annular recesses around the same,while in Fig. 3, the piston 2 has channels through the same.

Having fully described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In an explosive engine, a cylinder casing havin an air retaining chamber and a piston with an air channel extending around its crank end adapted to convey a charge of atmospheric air into said chamber on the outstroke of said piston, said casing having an air inlet port on its side opposite to said chamber and communicating'with said channel at said outstroke position whereby air is caused to travel around the piston to cool the same before reaching said chamber, said casing having a charge passage with an opening at each end into said cylinder, said piston having an annular channel at its compression end adapted to connect said chamber and said passage on the instroke of said piston.

2. In an explosive engine, a cylinder casing having an air retaining chamber and a piston with a chanel extending around its crank end adapted to convey a charge of atmospheric air into said chamber on the outstroke of said piston, said casing having an air inlet port on its side opposite to said chamber and communicating with said channel at said outstroke position whereby air is caused to travel around the piston to cool the same before reaching said chamber, said casing having a charge passage with an opening at each end into said cylinder, said piston having an annular channel at its compression end adapted to connect saidchamher and said passage on the instroke oisaid piston whereby sald air passes around said compression end of said piston to 0001 said latterend.

3. In ant-internal combustion engine means for alternating explosive charges with charges: of; atmospheric air into the compression and explosion chambers of the en-. ginex prior to ignition of said explosive charges, said means embracing an air chams her and anairinlet portand a pistonprovidedwith meansfforconnecting the same,; Silld first means also embracing a'passage having ports: enterln'gg two :parts of the ens gine cylinder, said piston havi'ngqneans for connecting said: chamber and said passage saidlsecond means consistingofan annular channelin the crank endiof: said piston;
